Final answer:
Chlorine, sulfur, and silicon, as chlorine is a gas and a halogen, sulfur forms an ion with a charge of -2, and silicon is a metalloid. Each element meets one of the criteria listed.The correct option is B.
Step-by-step explanation:
The question requires us to identify a group of elements that satisfy several criteria: at least one metalloid, one element that forms an ion with a charge of -2, one that is a gas, and one that is a halogen.
Let's analyze each option against the criteria:
A) Oxygen, fluorine, and aluminum: Oxygen is a gas and forms an ion with a charge of -2, fluorine is a halogen, but aluminum is a metal, not a metalloid.
B) Chlorine, sulfur, and silicon: Chlorine is a gas and a halogen, sulfur forms an ion with a charge of -2, and silicon is a metalloid.
C) Arsenic, oxygen, neon, hydrogen: Arsenic is a metalloid, oxygen forms an ion with a charge of -2, neon is a noble gas (not considered in the group of typical non-metal gases), and hydrogen is a gas but not a halogen.
D) Silicon, magnesium, neon, iodine: Silicon is a metalloid, iodine is a halogen, neon is a noble gas, but no element here forms an ion with a charge of -2.
Thus, the correct answer is B) Chlorine, sulfur, and silicon because each element satisfies one of the criteria respectively.
